DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a silver halide color light-sensitive material and a photographic unit (film with lens), and more particularly, to a high image quality, a high print yield, a small generation of flare, and an influence of flare. And a photographing unit.

[0002]

2. Description of the Related Art In recent years, silver halide color light-sensitive materials (hereinafter simply referred to as "light-sensitive materials") have been used for photographing (image exposure).
In order to more efficiently and later perform development processing and printing on photographic paper with high accuracy, there is a proposal to record information on photographing conditions and the like on a photosensitive material and to utilize the information effectively.

US Pat. No. 4,947,196 and WO 90/04254 disclose a roll-shaped film and a magnetic head having a magnetic layer containing magnetic particles capable of magnetic recording on the back surface of a photographic film. An imaging camera having the same is disclosed. According to the above-described improved technology, the identification information of the type and maker of the photosensitive material, information on the conditions at the time of photographing, information on the customer, information on the printing conditions, information on the conditions for additional printing, etc. are recorded on the magnetic layer on the film. By magnetically inputting / outputting the data, it is possible to improve the print quality, increase the efficiency of the printing operation, increase the efficiency of the lab work, and the like.

No. 165166 discloses that the film width of a roll-shaped color photographic material for photography is reduced to 15 to 15 mm.
35 mm or 20 to 35 mm, and the photographing screen area is smaller than the conventional about 860 mm ² , and 300 to 700 m
there is a proposal of the small format to m ^2. According to these, the image quality is higher than that of a so-called "110 camera" or "disk camera", and a patrone or a camera can be made smaller than before, or a functional part not provided in a conventional camera can be added. is there.

Further, there is a demand from users for downsizing of the camera, and downsizing while maintaining high image quality has been widely studied. At present, a so-called 135-size roll film for general use is hindered in thinning a camera because it is loaded in a standard-format patrone. In order to reduce the size of the patrone, it is most effective and simple to reduce the thickness of the film, that is, the photosensitive material. This can be achieved by making the thickness of the support of the photosensitive material thinner than before.

[0006] On the other hand, the standard size of the 135-size patrone is currently limited to 36 shots. There is a request to put more image information in one patrone,
This can also be achieved by making the thickness of the support of the photosensitive material thinner than before.

13042... 0002 to 0008 With the miniaturization of the camera together with the miniaturization of the camera, the distance between the photographic lens and the photographic film is shortened, the optical path space between the photographic lens and the photographic film is compressed, and the aperture is reduced in size. Be transformed into

On the other hand, the size of the photographing unit has also been reduced, and the “Konicari Konica Mini” manufactured by Konica Corporation succeeded in making the body of the photographing unit thinner by making the patrone thinner than the standard 135 size standard. The Konica Motto Mini has achieved further miniaturization by devising the layout inside the shooting unit itself.

When the proposal of the small format is applied to a photographing unit, the use of a short focus lens becomes possible, that is, the distance between the lens and the photographic film can be shortened, and the height of the patrone can be reduced. There is a merit that can be made.

However, due to the miniaturization, the influence of the flare of the photographing lens increases, and the influence of the re-reflection of the reflected light on the photographic film surface becomes significant.

In particular, in a photographing unit using a simple plastic lens, not only the problem of significant flare occurrence but also the aperture portion is curved to reduce the influence of distortion of the plastic lens. Is a factor that increases the effect of re-reflection of light reflected from the photographic film surface.

Further, in the photographing unit, as shown in Japanese Patent Application Laid-Open No. 5-210151, the photographic film is transferred from the film storage chamber to the aperture in order to prevent abrasion caused by rubbing between the photographic film and the plastic body of the photographing unit. Although a bent gap is provided in the feeding path, there is a disadvantage that a part of the reflected light on the surface of the photographic film passes through the gap during photographing, and fog is given to an unexposed photographic film.

The problems caused by the flare light and the reflected light from the photographic film surface are as follows.
It is remarkable for a photosensitive material having a high sensitivity and a high image quality of 60 to 800, and an improvement is desired.

On the other hand, the reduction in the size of the photographing screen increases the rate of enlargement (enlargement) of prints on photographic paper.
Image quality compared to printing from 35 size standard shooting screen,
Particularly, there is a problem that sharpness is deteriorated.

There is a technique for preventing and improving irradiation and halation by adding a dye to a photographic color light-sensitive material. However, it has been found that not only the sensitivity is reduced but also the effect of improvement is limited. Also, the dimensional stability of the photographic support against heat, humidity and curl is greatly affected, and the purpose cannot be achieved with the cellulose ester-based support currently used.

Further, the photographing unit has increased the opportunities for photographing in which ordinary users can easily enjoy photographs, but simple plastic lenses, fixed shutter speeds, fixed apertures, simple plastic bodies, manual winding, simple strobes, etc. With this configuration, prints such as focus failure and exposure failure occur more frequently than when a normal camera is used, and the so-called print yield is reduced.

When the amount of the polyalkylene glycol is less than 3% by weight, the curl after development processing cannot be obtained and the stretchability is further reduced, so that the mechanical strength required as a film cannot be obtained. On the other hand, if it exceeds 10% by weight, a film having sufficient mechanical strength cannot be obtained due to the low mechanical properties of the polyalkylene glycol.

Saturated aliphatic dicarboxylic acids are also effective in improving curl.

It is preferably from 3 to 25 mol% based on the bond.
As long as the amount of the aliphatic dicarboxylic acid is within the above range, if the copolymerized polyester contains an aliphatic dicarboxylic acid as a monomer unit, the curl of the photographic film can be easily eliminated, The transparent support can be provided with practical heat resistance.

In addition, the antioxidant can be used alone, or two or more thereof can be used in combination.

The transparent support is provided with a dye in the photographic support for the purpose of preventing a light piping phenomenon (edge fogging) which occurs when light enters the transparent support provided with the photographic emulsion layer from an edge.

The biaxially stretched film obtained as described above is usually heat-set at 150 to 240 ° C. and cooled. In this case, it may be relaxed in the vertical and / or horizontal direction if necessary.

The transparent support in the present invention may be a single-layer film or sheet formed by the above-described method, or may be formed by co-extrusion or lamination with another material. It may have a multilayer structure laminated with a film or sheet formed by a technique, but the latter is effective for curling prevention.

To the sixteenth layer (second protective layer) of Sample 101, Exemplified Dye-1 (yellow), Dye-7 (magenta), and Dye-9 (cyan) were appropriately added, and the surface reflectances are shown in Table 3. Samples 102 to 104 were produced with the above changes. Incidentally, the photographic sensitivity was adjusted by the amount of silver halide applied to each photosensitive layer so that approximately ISO = 100.

Samples 101 to 104 were prepared using Konica Big Mini
Super BM-S100 (Shooting screen area 493mm ² )
After taking 100 scenes under semi-backlit light, development and printing were performed, and the degree of the flare scene was visually ranked in four stages.

A: not worried at all B: not worried at all C: slightly worried D: very worried Table 3 shows the results.

[0207]

[Table 3]

Samples 101 and 103 were placed in a normal 135 mm
When tested with a size (24 × 36 mm), there is no problem with the B rank, but the effect of the present invention is remarkably exerted on the problem of flare that tends to occur when the screen area is reduced.

Example 2 Samples 201 to 204 were prepared by changing the support in Example 1 to polyethylene naphthalate (PEN), and the same evaluation as in Example 1 was performed. The camera used was Konica Big Mini BM-301 (photographing screen area: 864 mm ² ). Table 4 shows the results.

[0210]

[Table 4]

As shown in the table, when the support is TAC, the problem is small in B rank, but the effect of the present invention is remarkable in the photosensitive material using PEN as the support.

Example 3 A sample prepared in Example 1 was used as a photographing unit with a lens (Konica Motto Mini: aperture curvature R = 110 mm, R
= 150 mm), and the same evaluation as in Example 1 was performed. Table 5 shows the results.

[0213]

Although the problem is small when the curvature R value is large, the effect of the present invention is great for a camera having a smaller curvature R value.

Example 4 In the same manner as in Example 1, the dye addition amount of the sixteenth layer (second protective layer), the method of sensitizing silver halide in each emulsion layer, and the coating amount thereof were adjusted to obtain a photographic sensitivity of 400. Adjusted to be. Photographing was performed using Konica Big Mini BM-301, and the same evaluation was performed.

[0216]

[Table 6]

Although the problem is small at ISO = 100, the configuration of the present invention is remarkably effective against the problem that occurs when ISO = 400.

Example 5 A sample in which the support of the sample 404 of Example 4 was changed to PEN was prepared and loaded into a lens-equipped photographing unit (Konicari Konica AD: screen area 493 mm ² , aperture curvature R = 100 mm). Was taken. As a result of the development processing, the flare scene was at a level that was not bothersome.
